The 43-year-old founder of the Skinnygirl cocktail empire is expanding her presence in the kitchen with her own brand of appliances — starting with blenders.

Frankel is partnering with New York-based Sensio, maker of colorful Bella- branded kitchen gadgets, sold in Target, JCPenney and Walmart.

Her new line of blenders, costing $24.99 a pop, will be sold as Skinnygirl by Bella. The line will launch on QVC on Nov. 9 and will roll out to Sam’s Club stores next year.

Frankel, who parlayed her “Real Housewives of New York” fame into a low-calorie drink line, set her sights on appliances after expanding into other health and wellness products, including nutritional bars, popcorn and even shape wear.

Frankel is returning to RHONY and focusing on Skinnygirl after a failed talk show.

“Housewares is the perfect fit for Skinnygirl,” she said in a statement. “Appliances in your home should encourage a healthy lifestyle, be practical, innovative and easy to use for people on the go.”

Shae Hong, the 37-year-old CEO of Sensio, believes the Skyinnygirl brand is even bigger than Frankel.

“Part of it is Skinnygirl isn’t just about Bethenny Frankel, but it’s a brand in itself,” he told The Post.

Hong said healthy-living related appliances were the hottest thing in the appliance category, replacing single-cup coffeemakers. Sensio is on track for $200 million in annual sales, according to Hong.

“Young people are in tune with health and they’re counting nutritional numbers on their iPhones and Fitbits,” said Hong.
